#1 Post by sugar777 »

Hi all, I have been trying different solutions by googling these errors but until now I haven't been able to fix this situation, any assistance will be really appreciated people!

Note: It worked quite well until a few days it just sopped working when I was trying to get latest version of GNS3.

Hey hey, many thanks for the link you sent me. I will definitively read it... so based on the output I've submitted, do you think I just broke my Debian install? should I back up and fresh install? or what would you recommend me?

thanks again

Virtualbox has a Debian repo.
MS repos "should" be OK to add.

Other than that do NOT mix Debian and Ubuntu repos, ever.
